Abstract

A heat exchanger in which a header and tank construction comprises separate header and tank portions which are used in combination to form a heat exchanger unit. End caps for the header and tank construction and baffles to form partitions or chambers within the header and tank construction are inserted in grooves formed in the separate header and/or tank portion(s). The heat exchanger assembly comprises spaced combined header and tank constructions between which extend a plurality of tubes which are inserted in slots in the header portions. An area of the header portion can have a plurality of center portions and slots between adjacent center portions for the tubular elements. The apexes of each center portion between the tubular element slots have a flattened area and there are side portions running downward from the center portion apex flats which also are substantially flattened.

Dependent claims

A heat exchanger comprising:

spaced generally parallel header and tank constructions;
a plurality of tubular elements whose opposite ends are connected to the header and tank constructions and extend between the header and tank constructions;
each of the header and tank constructions comprising a separate header portion and a separate tank portion, the separate header portion and separate tank portion being adapted to be joined to form the spaced generally parallel header and tank constructions of the heat exchanger;
wherein ends of the header portion have end aligning tabs which can be bent over to align the separate header portion and separate tank portion;
and
end caps and at least one baffle plate which are inserted in grooves in an inner surface of the separate header portions and the separate tank portions;
wherein tubular elements are inserted in elongated, spaced receiving slots in the separate header portion surfaces of the header and tank construction and side tabs are adjacent to grooves in the header portion for the baffle plates.
